Contact Rich Measures, I made a QSK board using optoisolators & a 
jennings relay that he provided the schemetics for. I used that with 
my SB220 and it worked flawlessly for years. I finally sold the amp 
after 10 years of hard use and the QSK board and the tubes were in 
fine shape when I sold that amp. Only perpetual bugger with that amp 
was the bandswitch. I finally made my own switching Arrangement which 
was much heftier & didn't arc & die.

2Nd heathkit kit for me, the first was a H-8 I built and ran a 
bulletin board on.
